  29 ### The default rule
  30 #
  31 # Note: Target `all-local' must not depend on target '$(srcdir)$(PACKAGE).pot',
  32 # otherwise packages like GCC can not be built if only parts of the source have
  33 # been downloaded.
  34 #
  35 # Note 2: We aren't gcc, we are ELinks. And I want that dependency ;-). --pasky
  36 #
  37 # Note 3: I changed my mind, it is really annoying if you just insert one line
  38 # and suddenly you have tons of changes in all the .po files updating the line
  39 # informations. --pasky
  40 #
  41 # $(CATALOGS) is empty if --disable-nls. Beats using *-(yes|no) targets.
  42
  43 all-local: $(CATALOGS)

  46 ### Creating the template po template file
  47 #
  48 # This pulls in _all_ .c and .h files in the src directory. Even files that has
  49 # not been added to the git repo. Beware of junk entries!

  67 #
  68 # Update by merging all .po files with the .po template master file.
  69 #

  71 # either <lang> or <lang>.po when calling make. Example: make update-po PO=is
